These days many of us are trying to find ways to save money as much as possible. Reducing electricity bills is one of the ways that helps. The best option currently is to sue renewable energy from solar cells. It is widely accepted for its quality and safety for users and is likely to be more prevalent the near future.
The electric used everywhere is a light. If you are looking for a way to reduce electricity bill, we recommend Indoor Solar Lighting.
Efficiency of indoor solar lighting
1) Work 24 hours a day
Indoor solar light uses Lighting Hybrid AC/DC device to keep the light running 24 hours a day.
- With sunlight: Lighting Hybrid AC/DC is powered by a solar panel to make the light work
- With low sunlight: Lighting Hybrid AC/DC is powered by a solar panel and mixed with electricity from power lines.
- Without sunlight: Lighting Hybrid AC/DC is powered by a power line.
2) Reduce electricity bills from power lines up to 37%
Example case: use 6 of 12w LED lights with 12 working hours
Electricity bill (1 unit = 4 baht)
Electricity bill (day) 0.864 x 4 = 3.456 baht/day.
Electricity bills (month) 3.456 x 30 = 103.68 baht/month.
Electricity bills (year) 3.456 x 365 = 1261.44 baht/year
If using electricity from a solar panel of 40 W, amount 1 panel
Can generate electricity: 40 x 4 = 160 w/day
Therefore, it uses electricity from the power line: 864 – 160 = 704 w / day or 0.704 unit / day.
Electricity bill (1 unit = 4 baht)
Electricity bill (day) 0.704 x 4 = 2.816 baht / day.
Electricity bill (month) 2.816 x 30 = 84.48 baht / month
Electricity bill (year) 2.816 x 365 = 1027.84 baht / year
Reduce electricity costs from power lines (1261.44 – 1027.84) x100 / 1261.44 = 18.51%
If using electricity from two 40 W solar panels
Can generate electricity: 40 x 4 x 2 = 320 w / day
Therefore, it uses electricity from the power line: 864 – 320 = 544 w / day or 0.544 unit / day.
Electricity charge (1 unit = 4 baht)
Electricity bill payment (day) 0.544 x 4 = 2.176 baht / day.
Pay electricity bills (month) 2.176 x 30 = 65.28 baht / month.
Pay for electricity (year) 2.176 x 365 = 794.24 baht / year
Reduce electricity costs from power lines (1261.44 – 794.24) x100 / 1261.44 = 37.04%
3) Solar light is equipped with accessories for convenience
- Remote control to on / off the solar light + on / off switch
- Able to control to on / off the solar light up to 10 meters.
